Fruit: Cones are ovoid, 3 to 6 inches long, sessile, red-brown in color, armed with a slender prickle. Maturing August to September.
Twig: Stout, orange in color, turning black. Buds often covered with resin.
Bark: Very dark (nearly black) on young trees, developing cinnamon-colored plates and deep furrows.
